May 28, 1935 TOY Filed Jan. 21, 1955 2 Sheets-Sheet 2 Inventov AttomeyPatented May 28, 1935 mm STATES arms" I 1 Claim.

This invention relates to a toy boat and aims to provide a boat whichsimulates the movement of a fish in the water and the object of theinvention resides in the provision of a spring motor actuated mechanismwithin the body to oscillate a propeller in imitation of a fish tail.

Further objects of the invention are to provide a toy boat of thischaracter which is exceedingly simple in its construction, inexpensiveto manufacture, easy to manipulate, and thoroughly reliable forentertaining children. 7

With the foregoing and other objects in view the invention consists of anovel construction, combination and arrangement of parts as will behereinafter more specifically described and illustrated in theaccompanying drawings, wherein is disclosed an embodiment of theinvention, but it is to be understood that changes, variations, andmodifications may be resorted to without departing from the spirit ofthe claim hereunto appended.

In the drawings wherein like characters designate like parts throughoutthe several views:

Figure 1 is a side elevation of the device in accordance with thepresent invention.

Figure 2 is a detailed vertical section thereof.

Figure 3 is a detailed horizontal section taken substantially on line3-3of Figure 1.

Figure 4 is an enlarged fragmentary horizontal section through theescapement mechanism.

Figure 5 is an enlarged perspective View of the forward end of thepropeller attached to the propeller shaft.

Referring to the drawings in detail, it will be seen that the numeral 6denotes a closed hollow body of the hull of the toy boat formed insimulation of the body of a fish. In the hollow body is a frameconsisting of a flat top plate 1 and a fiat bottom plate 8 connectedtogether by the vertical end rails 9. The body 6 is preferably formed ofmetal and the bottom plate 8 of the frame is anchored to the bottom ofthe body 6 preferably by welding or brazing.

A vertical stem H! has the lower end thereof journaled in the bottomplate 8 of the frame as at l I, and an intermediate portion of the stemis journaled in the top plate 7 while the upper end of the stem l0extends through an opening I2 in the body and has a winding piece l3 onthe projecting end thereof. The stem I0 is caused to rotate by a springmotor l4 carried thereon. The stem I!) also has a relatively large gearwheel l5 secured thereto which meshes with the pinion gear I6 fixed tothe auxiliary stem IT. The ends of the auxiliary stem I! are rotatablymounted in the upper plate 1 and the lower plate 8 respectively of theframe. There is also an escapement gear l8 fixed to the auxiliary stemI1 below the pinion gear 16.

The escapement mechanism includes a rockable 5 arm is having the upperend thereof rockably mounted in the upper plate 1 of the frame, whilethe lower end is rockably mounted in the lower plate 3 of the frame. Theconventional or usual rocking escapement pawls 20 extend from the op- 10posite sides of the rocking arm I 9 and alternately engage with theteeth of the escapement gear 18 to impart a rocking motion to the armI9.

Above the water line 35, the rear end of the hollow body 6 is formedwith a slot 20 disposed in a transverse direction. One end of anoscillating propeller shaft 2! extends through the slot and coupled tothe projecting end of'the propeller shaft by means of a pin 22 is arelatively fiat flexible propeller 23 that simulates the tail of a fishin configuration. The body portion of the fish tail propeller ispreferably formed of rubber although it may be made of any desiredflexible material. The inner end of the oscillating propeller shaft 2|is fixed to the rocking arm l 9 as at 24 so that when the arm rocks anoscillating motion willbe imparted to the propeller shaft and translatedto the fish tail propeller .23. v To prevent water from splashing intothe body 6 from the oscillations of the propeller there is a bridge wall25 under the slot 20, the opposite edges of which are secured to theopposed walls of the body 6. Above the slot there is another bridge wall26 mounted in a manner similar to the lower bridge wall 25 and for thesame purpose. The bridge wall 25 flares outwardly and downwardly so thatWater may drain backwardly to the rear of the body and out through theslot.

A rudder 27 is fixed as at 28 to the lower end of the steering pin 29rotatable in an opening 30 in the body 6.

From the above detailed description it will be obvious that when thespring motor I4 is wound and released the said motor will cause anoscillating movement to be imparted to thetail propeller 23 so that whenthe toy is in the water it will be propelled forwardly in simulation tothe swimming movement of a fish.

Having described the invention, what is claimed as new is:

A toy boat comprising a closed hollow body, said body being formed witha slot at the rear end above the water line, a plate secured on theinner side of the lower portion of said body, a

pair of spaced upstanding supports fixed to said V plate, a second platesecured to the free end of said support, a rotatably mounted stem insaid plate extending upwardly through the upper portion of said body andhaving a handle on the 5 free end thereof, a spring motor secured tosaid stem, between said plates, a large gear fixed to said spring motor,a shaft rotatably mounted between said plates adjacent said stem, apinion gear on said shaft, in mesh with the motor gear,

an escapement gear on said shaft, an escapement pallet extending throughthe slots in the body and having a tail propeller secured to the outerend thereof whereby the tail propeller is directly actuated from theescapement gear, and a bridge wall across the rear end of the body underthe slot to prevent water from entering the body.

YUZABUBO HIROSE.
